OZONE-PRODUCING APPARATUS.

Specification of Letters Patent. original application filed September 22, 1908, Serial No. 454,260. Divided and this application filed s p- Patented May 23, 191 1 tember'29, 1910. Serial No. 584,434.

To all whom it may concern: 'Be it known that I, OCTAVE PATIN, a c1t1- zen of the Republic of France, residing at and the more diifusely they are spread, the

greater will be this output, and numerous devices have been proposed with this result in view. When the contact between the isolating wall of the chamber of ozonization and the electrodes is arranged along a contact-line, brush discharges are formed which are evenly distributed. When the contact is obtained by means of sharp points, the

' brush discharges are relatively more accen-.

tuated, and they are all the more so the sharper thepoints are. In order to obtain, instead of rush discharges, a luminous sheet, it is necessary for the contact to take place in equally distant points which are as numerous and as close together as pomible; and it is moreover necessary that the surface of the electrodes, instead of being pointed, be rounded in such a manner that its points of contact are tangential points.

It is the aim of the present invention to satisfy, these conditions, providing, at the same time, a device which possesses great advantages, such as simplicity and economical establishment.

7 It will be evident, furthermore, that the new device which produces anv even and intense luminous sheet subjects the electrodes-to less heat, whereby both the out ut and the durability of the apparatus are increased.

The accompanying v drawings represent one form of the device which is shown, for

purposes of illustration, applied to a sterilizing ozone apparatus, '5. e., to an apparatus for the ozonization of water in which the outflow of watercauses at the same time the production of ozone and its mixture with the liquid, wh1le the stopping of the circu-' lation of water interrupts the production of ozone.

Figure 1 shows the Whole of the aforesaid apparatus. Fig. 2 shows in vertical sectlon 1ts details on a larger scale and represents especially the whole of the ozone I apparatus itself together with its accesso ries. Fig. 3 is a detailed view of the electrodes. Fig. 4 represents a different view of the device for mixing water and ozone.

In order to accomplish the object of the invention, I use two concentric tubes, m and n, of glass or other suitable material which is at the same time insulating and resistant.

The intermediate space between the two glass tubes constitutes the ozonization chamber which is provided at one of its ends, 8,

with any suitable device, for. controlling the v V entrance of the air which is to be oz'onized, and at its other end, P, with a device to control the outflow of the air which has been subjected to the influence of the electric efiluvia. Before passing through the ozone I apparatus, the air may be freed from the dust which it holds in suspension by means of a purifier, t, which may consist simply of a cotton plug or its equivalent, arranged in the socket which forms the extreme end of the ozone apparatus.

The inner electrode may be formed out of a simple metal rod, 071), which frictionally engages the inner tube, m. The outer electrode is formed from a wire n of aluminum or its equivalent, which is first rolled up as a coil. the coil being then, in its turn, rolled in spiral form around the tube n. The adjacent wire helices which form the coil, as

, sheet rather than in the form of brush dis- 1 charges. r In order to avoid the oxidatlon of the outer electrode and, consequently,v to ncrease its yield and durability, this electrode is, in its turn, preferably inclosed in an outer glass tube, 0, which is concentric to the tubes m and n. The tube 0 is provided at each end with a metal cap or socket p, 22

The electrode n is electrically connected with the socket p, and the electrode m 1s similarly connected with the socket 79 and the sockets p, p are connected respectlvely with the two poles of an electric circuit. The air can pass into the ozone apparatus only through the annular space 9, which is traversed by the efiluvia and has no direct contact whatever with the electrodes which, therefore, will not oxidize and which Wlll retain their hi h yield. 0

The essential part of the inventlon consists of forming in the ozone apparatus one of the electrodes of a metal wire which is but to a small extent subject to oxidatlon and which is first rolled up in the shape of a coil, this coil bein in its turn, wound 1n the shape of a spira around the chamber of ozonization. The result of this construction is a multitude of tangential points of contact in rounded surfaces, instead of a line of contact or points of contact in sharp points, which has for effect the diffuse spreading of the electric efiluvia 1n much more important proportions than with the previous devices. The result is that, mstead of producing brush discharges, the efiiuvla yield a luminous sheet, and that, at the same time, the electrodes are subject to much less heat than in the case of the hitherto employed means, whereby the output of the apparatus is considerably increased While the durability of the electrode is prolonged. Moreover, as is evident, the manufacture is most economical since manual labor has been reduced to a minimum. This new device constitutes, therefore, a notable improvement with regard to simplicity and economy of .establishment as Well as to that of yield and working durability.

Figs. 1 and 2 represent the application of the object of the invention to an ozone apparatus for water or any other liquid, in which the establishment or the interruption of the passage of water causes automatlcally the establishment or the interruption of the production of ozone and its mixture with water. For this purpose the tube K is fed .by a water conduit which is under pressure and which is provided with an air valve at the upper part. I arrange, preferably at the interior of the tube K other devices for atomizing water and mixing With ozonized air, such as the conic adjustment, 7', or the device illustrated in Fig. 4' formed by a ball, for example of glass, pierced by a great number of infinitely small holes, in the interior of which the water inlet pipe, 0Z, terminates in a point a short distance above the pipe, 0, which has a wider mouth-piece.

The liquid is sent into the apparatus under pressure, and it passes into the same through 5 a vertical pipe, 6, which ends in a point in a bell, a, in which the starting pipe d of the ozone apparatus ends also. The cock, h, on the other hand, which controls the introduction of water, is combined with an interrupter which controls the electric circuit furnished by a source, 1-, so as to establish or interrupt, by 'one single operation, the electric current as well as the current of liquid.

The apparatus works as follows: In order to cause the same to yield ozonized water, the cock is o ened and the water streams into the chamlier, a. At the same time the electric current is established between the electrodes m and n and traverses the annular space, g, in the form of efliuvia which causes the production of ozone. The ozonized air spreads through the pipe d into the chamber a, where a first mixture with water which streams from the pipe I) is eifected. The outflow of water through the pipe 0 produces an air valve, and the ozonized air passes into the pipe 0 at the same time as the water. Inasmuch as the latter is considerably divided, the mixture becomes more and more intimate. Thesame takes place in y.

t and I? represent the cotton plugs or their equivalents, destined to retain the impurities of the solid particles, and to perform the-mechanical filtration of air and water.

One of the principal advantages of this device results from its yield which is increased on account of the fact that there is neither any passage of non-ozonized water nor any production of non-utilized ozone.
